Four big US utilities have each reported in recent days substantial carbon dioxide emission reductions over the past few years due principally to an increase in the use of natural gas, renewable generation and to the sale or closure of coal-fired assets.

The four utilities — Duke Energy, Southern Company, American Electric Power and Xcel Energy — have reported CO2 reductions of between 28% and 37% over an 11-year period starting in 2005. Each of the four have made changes to their generating portfolios to take advantage of lower-price renewables that attract federal and state-level subsidies but which also, the utilities say, increasingly appeal to their customers.
